i have a somewhat similar setup and had to play around a little bit to get it to work right and look good. mine too was initally set at 640x480 and it looked awful. what i did: changed monitor driver to ''standard monitor types''|''digital flat panel''|800x600. sure, higher res would be nicer but i discovered that 800x600 works well on a tv since i'm viewing from a farther distance. good luck.
